Abstract (en)
[origin: WO2015148248A1] The compositions described herein provide flexible polyurethane injection molded foam made from the reaction product of at least one polyol, at least one isocyanate, and at least one chain extender, where the polyurethane has: (a) a weight average molecular weight of 120,000 to 500,000, and (b) a dispersity (Mw/Mn) of 1.85 to 2.51. The compositions further include superior foams where the flexible polyurethane injection molded foam has: a vertical rebound, as measured by ASTM D2632, of at least 30%; a compression set at room temperature, as measured by ASTM D395, of no more than 25%; a compression set at 50C, as measured by ASTM D395, of no more than 50%; and an Asker C hardness, as measured by ASTM D2240, of 40 to 65. Also provided are process of making the same and articles made from the same.
